IMPRbVEMENT lN APPARATUS FOR RAISING WATER.

Specification forming part of Letters Patent N 0. 143,882, dated October21, 1873; application filed September 24, 1873.

To all whom it may concern:

Be it known that I, LORENZO CnAsE, of Portland, in the county ofCumberland and in the State of Maine, have invented certain new anduseful Improvements in Apparatus for Raising Water; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings making a partof this specification, in which- Figure 1 is a perspective view of myapparatus as arranged for use. Fig. 2 is a vertical central section ofthe same upon a line parallel to the front of the apparatus; and Fig. 3

is a like view of the same, showing a modifi cation in the constructionand arrangement of parts.

Letters of like. name and kind refer to like parts in each of thefigures.

The object of my invention is to enable water to be raised by means ofthe direct action of steam, and. without the intervention of .the usualoperative mechanism; and it consists, principally, in two or morechambers, provided with suitable openings and apparatus for theautomatic and alternate admission and emission of steam and air, incombination with two or more water-chambers provided with ingress andegress openings and valves, substantially as and for the purposehereinafter specified. It consists, further, in the construction andrelative arrangement of the air and water chambers, and the air, steam,and water ports,

substantially as and for the purpose hereinafter shown. In the annexeddrawings, Aand A represent two compartments, having, preferably, a

tween and connects said chamber to the opposite similar chamber I thatis connected to or with the opposite compartment. From the upper sideand center of the cross-pipe K a discharge-pipe, L, extends upward andoutward, and, at some suitable point between its outer end and said pipeK, is provided with an air-chamber, M, of usual construction.

The apparatus being arranged so as to cause the chambers I and I to besubmerged in water, its operation is as follows: Upon the admission ofsteam to one of the compartments A, the air contained therein iscompressed and forced downward into the water-chamber I, and, closingthe'inlet-valve i, forces the water contained within said chamber intoand through the pipes K and L, from the latter of which said water isdischarged. Steam is now out off from the compartment A and admitted tothe second compartment A, where it performs the same office as beforedescribed, while the steam contained in said compartment Ais permittedto escape through the exhaust-port E, so as to relieve the air of saidcompartment from pressure, after which the water without the chamber Iwill open the valve t" and flow inward until vsaid chamber is filled tothe level of the exterior surface of said water, the operations ofalternately filling and discharging said chambers being carried on so asto cause a substantially constant flow of water into the pipe L, whichflow is rendered uniform and constant by the action of the air-chamberM. In order to prevent the formation of a vacuum within the compartmentsA and A, an inwardopening valve, to, is placed within the lower side ofeach, and, whenever the pressure is greater Without than within, opensand per mits air to pass freely inward.

For use in mines, or other places where Water requires to be raised togreat heights, the apparatus may be arranged, as shown in Fig. 3, so asto cause one set of devices to receive the water at the height to whichit has been raised by the preceding set, and to pass it upward to thethird set, the number of the steam and water compartments, with theirconnecting mechanism, being limited only by the distance to'which wateris to be forced.

When desired, the compressing apparatus may be located at one point uponor above the surface of the ground, while the water-chambers may beplaced at suitable points within a mine, and connected with the formerby pipes having the necessary lengths.

The apparatus described is simple in con struction, efficient inoperation, costs materially less than ordinary pumping devices, andcan'be operated by persons possessing but slight skill. 7

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s- 1. Two or more chambers, provided with suitableopenings and apparatus for the automatic and alternate admission ofsteam and air, in combination with two or more waterchambers providedwith ingress and egress openings and valves, substantially as and forthe purpose specified.

2. The construction and relative arrangement of the air-chambers A andA, provided with the air-passages H and a and steam-ports d and E, andthe water-chambers I and 1, provided with the water-passages 13 and 7c,and discharge-pipes K and L, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this22d day of September, 1873.

LORENZO CHASE.
